753 bucket fully dumps and will not respond to drive

[U1300L]

753 when it starts the bucket goes into full dump and raises machine, the unit is non-responsive to any commands and will not drive or quit the dumping ?? Any thoughts or suggestions? One tech thought the master hydraulic solenoid was broken, and another thought it was the dump bucket solenoid. I checked the ohms on the bucket coil and it is 7 ohms (manual range is 4-6 ohm)

sounds like the pedal has over centered or linkage has come loose

No Pedals on this one. All done with the joy sticks except that the drive is still manual with the sticks. (not auto with the top part of the sticks).
